Foreword This is version 2.0.1 of the Linux Standard Base Core Specification for AMD64. An implementation of this version of 1

the specification may not claim to be an implementation of the Linux Standard Base unless it has successfully 2

completed the compliance process as defined by the Free Standards Group. 3

Introduction The LSB defines a binary interface for application programs that are compiled and packaged for LSB-conforming 1

implementations on many different hardware architectures. Since a binary specification shall include information 2

specific to the computer processor architecture for which it is intended, it is not possible for a single document to 3

specify the interface for all possible LSB-conforming implementations. Therefore, the LSB is a family of 4

specifications, rather than a single one. 5

This document should be used in conjunction with the documents it references. This document enumerates the system 6

components it includes, but descriptions of those components may be included entirely or partly in this document, 7

partly in other documents, or entirely in other reference documents. For example, the section that describes system 8

service routines includes a list of the system routines supported in this interface, formal declarations of the data 9

structures they use that are visible to applications, and a pointer to the underlying referenced specification for 10

information about the syntax and semantics of each call. Only those routines not described in standards referenced by 11

this document, or extensions to those standards, are described in the detail. Information referenced in this way is as 12

much a part of this document as is the information explicitly included here. 13

I. Introductory Elements

1

Chapter 1. Scope

1.1. General The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for 1

support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume 2

applications conforming to the LSB. 3

These specifications are composed of two basic parts: A common specification ("LSB-generic") describing those parts 4

of the interface that remain constant across all implementations of the LSB, and an architecture-specific specification 5

("LSB-arch") describing the parts of the interface that vary by processor architecture. Together, the LSB-generic and 6

the architecture-specific supplement for a single hardware architecture provide a complete interface specification for 7

compiled application programs on systems that share a common hardware architecture. 8

The LSB-generic document shall be used in conjunction with an architecture-specific supplement. Whenever a section 9

of the LSB-generic specification shall be supplemented by architecture-specific information, the LSB-generic 10

document includes a reference to the architecture supplement. Architecture supplements may also contain additional 11

information that is not referenced in the LSB-generic document. 12

The LSB contains both a set of Application Program Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs 13

may appear in the source code of portable applications, while the compiled binary of that application may use the 14

larger set of ABIs. A conforming implementation shall provide all of the ABIs listed here. The compilation system 15

may replace (e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and 16

may insert calls to binary interfaces as needed. 17

The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be 18

contained in this specification. 19

1.2. Module Specific Scope This is the AMD64 architecture specific Core module of the Linux Standards Base (LSB). This module supplements 20

the generic LSB Core module with those interfaces that differ between architectures. 21

Interfaces described in this module are mandatory except where explicitly listed otherwise. Core interfaces may be 22

supplemented by other modules; all modules are built upon the core. 23

Chapter 2. Normative References The specifications listed below are referenced in whole or in part by the Linux Standard Base. In this specification, 1

where only a particular section of one of these references is identified, then the normative reference is to that section 2

alone, and the rest of the referenced document is informative. 3

3.1. Relevant Libraries The libraries listed in Table 3-1 shall be available on x86-64 Linux Standard Base systems, with the specified runtime 1

names. These names override or supplement the names specified in the generic LSB specification. The specified 2

program interpreter, referred to as proginterp in this table, shall be used to load the shared libraries specified by 3

DT_NEEDED entries at run time. 4

Table 3-1. Standard Library Names 5

Library Runtime Name

proginterp /lib64/ld-lsb-x86-64.so.2

libc libc.so.6

libcrypt libcrypt.so.1

libdl libdl.so.2

libpthread libpthread.so.0

libgcc_s libgcc_s.so.1

libz libz.so.1

libncurses libncurses.so.5

libutil libutil.so.1 6

These libraries will be in an implementation-defined directory which the dynamic linker shall search by default. 7

3.2. LSB Implementation Conformance A conforming implementation shall satisfy the following requirements: 8

• The implementation shall implement fully the architecture described in the hardware manual for the target 9

processor architecture. 10

• The implementation shall be capable of executing compiled applications having the format and using the system 11

interfaces described in this document. 12

• The implementation shall provide libraries containing the interfaces specified by this document, and shall provide a 13

dynamic linking mechanism that allows these interfaces to be attached to applications at runtime. All the interfaces 14

shall behave as specified in this document. 15

• The map of virtual memory provided by the implementation shall conform to the requirements of this document. 16

• The implementation's low-level behavior with respect to function call linkage, system traps, signals, and other such 17

activities shall conform to the formats described in this document. 18

Chapter 3. Requirements

6

• The implementation shall provide all of the mandatory interfaces in their entirety. 19

• The implementation may provide one or more of the optional interfaces. Each optional interface that is provided 20

shall be provided in its entirety. The product documentation shall state which optional interfaces are provided. 21

• The implementation shall provide all files and utilities specified as part of this document in the format defined here 22

and in other referenced documents. All commands and utilities shall behave as required by this document. The 23

implementation shall also provide all mandatory components of an application's runtime environment that are 24

included or referenced in this document. 25

• The implementation, when provided with standard data formats and values at a named interface, shall provide the 26

behavior defined for those values and data formats at that interface. However, a conforming implementation may 27

consist of components which are separately packaged and/or sold. For example, a vendor of a conforming 28

implementation might sell the hardware, operating system, and windowing system as separately packaged items. 29

• The implementation may provide additional interfaces with different names. It may also provide additional 30

behavior corresponding to data values outside the standard ranges, for standard named interfaces. 31

3.3. LSB Application Conformance A conforming application shall satisfy the following requirements: 32

• Its executable files are either shell scripts or object files in the format defined for the Object File Format system 33

interface. 34

• Its object files participate in dynamic linking as defined in the Program Loading and Linking System interface. 35

• It employs only the instructions, traps, and other low-level facilities defined in the Low-Level System interface as 36

being for use by applications. 37

• If it requires any optional interface defined in this document in order to be installed or to execute successfully, the 38

requirement for that optional interface is stated in the application's documentation. 39

• It does not use any interface or data format that is not required to be provided by a conforming implementation, 40

unless: 41

• If such an interface or data format is supplied by another application through direct invocation of that application 42

during execution, that application is in turn an LSB conforming application. 43

• The use of that interface or data format, as well as its source, is identified in the documentation of the application. 44

• It shall not use any values for a named interface that are reserved for vendor extensions. 45

A strictly conforming application does not require or use any interface, facility, or implementation-defined extension 46

that is not defined in this document in order to be installed or to execute successfully. 47

Chapter 5. Terminology For the purposes of this document, the following terms apply: 1

archLSB 2

The architectural part of the LSB Specification which describes the specific parts of the interface that are 3

platform specific. The archLSB is complementary to the gLSB. 4

Binary Standard 5

The total set of interfaces that are available to be used in the compiled binary code of a conforming application. 6

gLSB 7

The common part of the LSB Specification that describes those parts of the interface that remain constant across 8

all hardware implementations of the LSB. 9

implementation-defined 10

Describes a value or behavior that is not defined by this document but is selected by an implementor. The value or 11

behavior may vary among implementations that conform to this document. An application should not rely on the 12

existence of the value or behavior. An application that relies on such a value or behavior cannot be assured to be 13

portable across conforming implementations. The implementor shall document such a value or behavior so that it 14

can be used correctly by an application. 15

Shell Script 16

A file that is read by an interpreter (e.g., awk). The first line of the shell script includes a reference to its 17

interpreter binary. 18

Source Standard 19

The set of interfaces that are available to be used in the source code of a conforming application. 20

undefined 21

Describes the nature of a value or behavior not defined by this document which results from use of an invalid 22

program construct or invalid data input. The value or behavior may vary among implementations that conform to 23

this document. An application should not rely on the existence or validity of the value or behavior. An application 24

that relies on any particular value or behavior cannot be assured to be portable across conforming 25

implementations. 26

unspecified 27

Describes the nature of a value or behavior not specified by this document which results from use of a valid 28

program construct or valid data input. The value or behavior may vary among implementations that conform to 29

this document. An application should not rely on the existence or validity of the value or behavior. An application 30

that relies on any particular value or behavior cannot be assured to be portable across conforming 31

implementations. 32

Other terms and definitions used in this document shall have the same meaning as defined in Chapter 3 of the Base 33

Definitions volume of ISO POSIX (2003). 34

Chapter 6. Documentation Conventions Throughout this document, the following typographic conventions are used: 1

function() 2

the name of a function 3

command 4

the name of a command or utility 5

CONSTANT 6

a constant value 7

I. Base Libraries

1

Chapter 1. Libraries An LSB-conforming implementation shall support some base libraries which provide interfaces for accessing the 1

operating system, processor and other hardware in the system. 2

Interfaces that are unique to the AMD64 platform are defined here. This section should be used in conjunction with the 3

corresponding section in the Linux Standard Base Specification. 4

1.1. Program Interpreter/Dynamic Linker The LSB specifies the Program Interpreter to be /lib64/ld-lsb-x86-64.so.2. 5

1.2. Interfaces for libc Table 1-1 defines the library name and shared object name for the libc library 6

Table 1-1. libc Definition 7

Library: libc

SONAME: libc.so.6 8

The behavior of the interfaces in this library is specified by the following specifications: 9

1.3. Data Definitions for libc This section defines global identifiers and their values that are associated with interfaces contained in libc. These 216

definitions are organized into groups that correspond to system headers. This convention is used as a convenience for 217

the reader, and does not imply the existence of these headers, or their content. 218

These definitions are intended to supplement those provided in the referenced underlying specifications. 219


18

This specification uses ISO/IEC 9899 C Language as the reference programming language, and data definitions are 220

specified in ISO C format. The C language is used here as a convenient notation. Using a C language description of 221

these data objects does not preclude their use by other programming languages. 222

1.7. Interface Definitions for libgcc_s The following interfaces are included in libgcc_s and are defined by this specification. Unless otherwise noted, these 688

interfaces shall be included in the source standard. 689

Other interfaces listed above for libgcc_s shall behave as described in the referenced base document. 690

_Unwind_DeleteException

Name

_Unwind_DeleteException — private C++ error handling method 691

Synopsis

void _Unwind_DeleteException((struct _Unwind_Exception *object)); 692

Description

_Unwind_DeleteException deletes the given exception object. If a given runtime resumes normal execution 693

after catching a foreign exception, it will not know how to delete that exception. Such an exception shall be deleted by 694

calling _Unwind_DeleteException. This is a convenience function that calls the function pointed to by the 695

exception_cleanup field of the exception header. 696

_Unwind_Find_FDE

Name

_Unwind_Find_FDE — private C++ error handling method 697

Synopsis

fde * _Unwind_Find_FDE(void *pc, (struct dwarf_eh_bases *bases)); 698

Description

_Unwind_Find_FDE looks for the object containing pc, then inserts into bases. 699


35

_Unwind_ForcedUnwind

Name

_Unwind_ForcedUnwind — private C++ error handling method 700

Synopsis

_Unwind_Reason_Code _Unwind_ForcedUnwind((struct _Unwind_Exception *object), 701

_Unwind_Stop_Fn stop, void *stop_parameter); 702

Description

_Unwind_ForcedUnwind raises an exception for forced unwinding, passing along the given exception object, 703

which should have its exception_class and exception_cleanup fields set. The exception object has been allocated by 704

the language-specific runtime, and has a language-specific format, except that it shall contain an _Unwind_Exception 705

struct. 706

Forced unwinding is a single-phase process. stop and stop_parameter control the termination of the unwind 707

process instead of the usual personality routine query. stop is called for each unwind frame, with the parameteres 708

described for the usual personality routine below, plus an additional stop_parameter. 709

Return Value

When stop identifies the destination frame, it transfers control to the user code as appropriate without returning, 710

normally after calling _Unwind_DeleteException. If not, then it should return an _Unwind_Reason_Code value. 711

If stop returns any reason code other than _URC_NO_REASON, then the stack state is indeterminate from the point 712

of view of the caller of _Unwind_ForcedUnwind. Rather than attempt to return, therefore, the unwind library should 713

use the exception_cleanup entry in the exception, and then call abort. 714

_URC_NO_REASON 715

This is not the destination from. The unwind runtime will call frame's personality routine with the 716

_UA_FORCE_UNWIND and _UA_CLEANUP_PHASE flag set in actions, and then unwind to the next frame and call 717

the stop function again. 718

_URC_END_OF_STACK 719

In order to allow _Unwind_ForcedUnwind to perform special processing when it reaches the end of the stack, 720

the unwind runtime will call it after the last frame is rejected, with a NULL stack pointer in the context, and the 721

stop function shall catch this condition. It may return this code if it cannot handle end-of-stack. 722

_URC_FATAL_PHASE2_ERROR 723

The stop function may return this code for other fatal conditions like stack corruption. 724


36

_Unwind_GetDataRelBase

Name

_Unwind_GetDataRelBase — private IA64 C++ error handling method 725

Synopsis

_Unwind_Ptr _Unwind_GetDataRelBase((struct _Unwind_Context *context)); 726

Description

_Unwind_GetDataRelBase returns the global pointer in register one for context. 727

_Unwind_GetGR

Name

_Unwind_GetGR — private C++ error handling method 728

Synopsis

_Unwind_Word _Unwind_GetGR((struct _Unwind_Context *context), int index); 729

Description

_Unwind_GetGR returns data at index found in context. The register is identified by its index: 0 to 31 are for the 730

fixed registers, and 32 to 127 are for the stacked registers. 731

During the two phases of unwinding, only GR1 has a guaranteed value, which is the global pointer of the frame 732

referenced by the unwind context. If the register has its NAT bit set, the behavior is unspecified. 733

_Unwind_GetIP

Name

_Unwind_GetIP — private C++ error handling method 734

Synopsis

_Unwind_Ptr _Unwind_GetIP((struct _Unwind_Context *context)); 735

Description

_Unwind_GetIP returns the instruction pointer value for the routine identified by the unwind context. 736


37

_Unwind_GetLanguageSpecificData

Name

_Unwind_GetLanguageSpecificData — private C++ error handling method 737

Synopsis

_Unwind_Ptr _Unwind_GetLanguageSpecificData((struct _Unwind_Context *context), uint 738

value); 739

Description

_Unwind_GetLanguageSpecificData returns the address of the language specific data area for the current stack 740

frame. 741

_Unwind_GetRegionStart

Name

_Unwind_GetRegionStart — private C++ error handling method 742

Synopsis

_Unwind_Ptr _Unwind_GetRegionStart((struct _Unwind_Context *context)); 743

Description

_Unwind_GetRegionStart routine returns the address (i.e., 0) of the beginning of the procedure or code fragment 744

described by the current unwind descriptor block. 745

_Unwind_GetTextRelBase

Name

_Unwind_GetTextRelBase — private IA64 C++ error handling method 746

Synopsis

_Unwind_Ptr _Unwind_GetTextRelBase((struct _Unwind_Context *context)); 747

Description

_Unwind_GetTextRelBase calls the abort method, then returns. 748


38

_Unwind_RaiseException

Name

_Unwind_RaiseException — private C++ error handling method 749

Synopsis

_Unwind_Reason_Code _Unwind_RaiseException((struct _Unwind_Exception *object)); 750

Description

_Unwind_RaiseException raises an exception, passing along the given exception object, which should have its 751

exception_class and exception_cleanup fields set. The exception object has been allocated by the 752

language-specific runtime, and has a language-specific format, exception that it shall contain an 753

_Unwind_Exception. 754

Return Value

_Unwind_RaiseException does not return unless an error condition is found. If an error condition occurs, an 755

_Unwind_Reason_Code is returnd: 756

_URC_END_OF_STACK 757

The unwinder encountered the end of the stack during phase one without finding a handler. The unwind runtime 758

will not have modified the stack. The C++ runtime will normally call uncaught_exception in this case. 759


The unwinder encountered an unexpected error during phase one, because of something like stack corruption. 761

The unwind runtime will not have modified the stack. The C++ runtime will normally call terminate in this 762

case. 763


The unwinder encountered an unexpected error during phase two. This is usually a throw, which will call 765

terminate. 766


39

_Unwind_Resume

Name

_Unwind_Resume — private C++ error handling method 767

Synopsis

void _Unwind_Resume((struct _Unwind_Exception *object)); 768

Description

_Unwind_Resume resumes propagation of an existing exception object. A call to this routine is inserted as the end 769

of a landing pad that performs cleanup, but does not resume normal execution. It causes unwinding to proceed further. 770

_Unwind_SetGR

Name

_Unwind_SetGR — private C++ error handling method 771

Synopsis

void _Unwind_SetGR((struct _Unwind_Context *context), int index, uint value); 772

Description

_Unwind_SetGR sets the value of the register indexed for the routine identified by the unwind context. 773

_Unwind_SetIP

Name

_Unwind_SetIP — private C++ error handling method 774

Synopsis

void _Unwind_SetIP((struct _Unwind_Context *context), uint value); 775

Description

_Unwind_SetIP sets the value of the instruction pointer for the routine identified by the unwind context 776

Appendix A. GNU Free Documentation License Version 1.1, March 2000 1

Copyright (C) 2000 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is 2

permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 3

A.1. PREAMBLE The purpose of this License is to make a manual, textbook, or other written document "free" in the sense of freedom: to 4

assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or 5

noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, 6

while not being considered responsible for modifications made by others. 7

This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the 8

same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. 9

We have designed this License in order to use it for manuals for free software, because free software needs free 10

documentation: a free program should come with manuals providing the same freedoms that the software does. But 11

this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or 12

whether it is published as a printed book. We recommend this License principally for works whose purpose is 13

instruction or reference. 14

A.2. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work that contains a notice placed by the copyright holder saying it can be 15

distributed under the terms of this License. The "Document", below, refers to any such manual or work. Any member 16

of the public is a licensee, and is addressed as "you". 17

A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied 18

verbatim, or with modifications and/or translated into another language. 19

A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the 20

relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and 21

contains nothing that could fall directly within that overall subject. (For example, if the Document is in part a textbook 22

of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of 23

historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or 24

political position regarding them. 25

The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant 26

Sections, in the notice that says that the Document is released under this License. 27

The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the 28

notice that says that the Document is released under this License. 29

A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification 30

is available to the general public, whose contents can be viewed and edited directly and straightforwardly with generic 31

text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available 32

drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats 33

suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup has been 34

Appendix A. GNU Free Documentation License

2

designed to thwart or discourage subsequent modification by readers is not Transparent. A copy that is not 35

"Transparent" is called "Opaque". 36

Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, 37

LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML 38

designed for human modification. Opaque formats include PostScript, PDF, proprietary formats that can be read and 39

edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not 40

generally available, and the machine-generated HTML produced by some word processors for output purposes only. 41

The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, 42

legibly, the material this License requires to appear in the title page. For works in formats which do not have any title 43

page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the 44

beginning of the body of the text. 45

A.3. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that 46

this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced 47

in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical 48

measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may 49

accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow 50

the conditions in section 3. 51

You may also lend copies, under the same conditions stated above, and you may publicly display copies. 52

A.4. COPYING IN QUANTITY If you publish printed copies of the Document numbering more than 100, and the Document's license notice requires 53

Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover 54

Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify 55

you as the publisher of these copies. The front cover must present the full title with all words of the title equally 56

prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the 57

covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim 58

copying in other respects. 59

If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit 60

reasonably) on the actual cover, and continue the rest onto adjacent pages. 61

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a 62

machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a 63

publicly-accessible computer-network location containing a complete Transparent copy of the Document, free of 64

added material, which the general network-using public has access to download anonymously at no charge using 65

public-standard network protocols. If you use the latter option, you must take reasonably prudent steps, when you 66

begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the 67

stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents 68

or retailers) of that edition to the public. 69

It is requested, but not required, that you contact the authors of the Document well before redistributing any large 70

number of copies, to give them a chance to provide you with an updated version of the Document. 71


3

A.5. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, 72

provided that you release the Modified Version under precisely this License, with the Modified Version filling the role 73

of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of 74

it. In addition, you must do these things in the Modified Version: 75

A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of 76

previous versions (which should, if there were any, be listed in the History section of the Document). You may 77

use the same title as a previous version if the original publisher of that version gives permission. 78

B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications 79

in the Modified Version, together with at least five of the principal authors of the Document (all of its principal 80

authors, if it has less than five). 81

C. State on the Title page the name of the publisher of the Modified Version, as the publisher. 82

D. Preserve all the copyright notices of the Document. 83

E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. 84

F. Include, immediately after the copyright notices, a license notice giving the public permission to use the 85

Modified Version under the terms of this License, in the form shown in the Addendum below. 86

G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the 87

Document's license notice. 88

H. Include an unaltered copy of this License. 89

I. Preserve the section entitled "History", and its title, and add to it an item stating at least the title, year, new 90

authors, and publisher of the Modified Version as given on the Title Page. If there is no section entitled "History" 91

in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title 92

Page, then add an item describing the Modified Version as stated in the previous sentence. 93

J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the 94

Document, and likewise the network locations given in the Document for previous versions it was based on. 95

These may be placed in the "History" section. You may omit a network location for a work that was published at 96

least four years before the Document itself, or if the original publisher of the version it refers to gives permission. 97

K. In any section entitled "Acknowledgements" or "Dedications", preserve the section's title, and preserve in the 98

section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. 99

L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or 100

the equivalent are not considered part of the section titles. 101

M. Delete any section entitled "Endorsements". Such a section may not be included in the Modified Version. 102

N. Do not retitle any existing section as "Endorsements" or to conflict in title with any Invariant Section. 103

If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and 104

contain no material copied from the Document, you may at your option designate some or all of these sections as 105

invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These 106

titles must be distinct from any other section titles. 107

You may add a section entitled "Endorsements", provided it contains nothing but endorsements of your Modified 108

Version by various parties--for example, statements of peer review or that the text has been approved by an 109

organization as the authoritative definition of a standard. 110


4

You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover 111

Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of 112

Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already 113

includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are 114

acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the 115

previous publisher that added the old one. 116

The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity 117

for or to assert or imply endorsement of any Modified Version. 118

A.6. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 119

4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the 120

original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice. 121

The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be 122

replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make 123

the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or 124

publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of 125

Invariant Sections in the license notice of the combined work. 126

In the combination, you must combine any sections entitled "History" in the various original documents, forming one 127

section entitled "History"; likewise combine any sections entitled "Acknowledgements", and any sections entitled 128

"Dedications". You must delete all sections entitled "Endorsements." 129

A.7. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace 130

the individual copies of this License in the various documents with a single copy that is included in the collection, 131

provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. 132

You may extract a single document from such a collection, and distribute it individually under this License, provided 133

you insert a copy of this License into the extracted document, and follow this License in all other respects regarding 134

verbatim copying of that document. 135

A.8. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a 136

volume of a storage or distribution medium, does not as a whole count as a Modified Version of the Document, 137

provided no compilation copyright is claimed for the compilation. Such a compilation is called an "aggregate", and 138

this License does not apply to the other self-contained works thus compiled with the Document, on account of their 139

being thus compiled, if they are not themselves derivative works of the Document. 140

If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less 141

than one quarter of the entire aggregate, the Document's Cover Texts may be placed on covers that surround only the 142

Document within the aggregate. Otherwise they must appear on covers around the whole aggregate. 143

A.9. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms 144

of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, 145

but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant 146

Sections. You may include a translation of this License provided that you also include the original English version of 147

this License. In case of a disagreement between the translation and the original English version of this License, the 148

original English version will prevail. 149

A.10. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. 150

Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate 151

your rights under this License. However, parties who have received copies, or rights, from you under this License will 152

not have their licenses terminated so long as such parties remain in full compliance. 153

A.11. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time 154

to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new 155

problems or concerns. See http://www.gnu.org/copyleft/. 156

Each version of the License is given a distinguishing version number. If the Document specifies that a particular 157

numbered version of this License "or any later version" applies to it, you have the option of following the terms and 158

conditions either of that specified version or of any later version that has been published (not as a draft) by the Free 159

Software Foundation. If the Document does not specify a version number of this License, you may choose any version 160

ever published (not as a draft) by the Free Software Foundation. 161

A.12. How to use this License for your documents To use this License in a document you have written, include a copy of the License in the document and put the 162

following copyright and license notices just after the title page: 163

Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of 164

the GNU Free Documentation License, Version 1.1 or any later version published by the Free Software Foundation; with the 165

Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being 166

LIST. A copy of the license is included in the section entitled "GNU Free Documentation License". 167

If you have no Invariant Sections, write "with no Invariant Sections" instead of saying which ones are invariant. If you 168

have no Front-Cover Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being LIST"; likewise for 169

Back-Cover Texts. 170

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel 171

under your choice of free software license, such as the GNU General Public License, to permit their use in free 172

software. 173
